Answer:
The portfolio beta is ![\alpha = 1.354](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%201.354)
Step-by-step explanation:
From the question we are told that
The first investment is ![i_1 = \$ 25,000](https://tex.z-dn.net/?f=i_1%20%3D%20%20%5C%24%2025%2C000)
The first beta is ![k = 0.8](https://tex.z-dn.net/?f=k%20%3D%20%200.8)
The second investment is ![i_2 = \$ 40,000](https://tex.z-dn.net/?f=i_2%20%3D%20%20%5C%24%2040%2C000)
The second beta is ![w = 1.7](https://tex.z-dn.net/?f=w%20%3D%20%201.7)
Generally the portfolio beta is mathematically represented as
![\alpha = \frac{ i_1 * k + i_2 * w }{ i_1 + i_2}](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%20%5Cfrac%7B%20i_1%20%2A%20%20k%20%2B%20i_2%20%2A%20w%20%7D%7B%20i_1%20%2B%20i_2%7D)
substituting values
![\alpha = \frac{ (25000 * 0.8) + ( 40000* 1.7 ) }{40000 + 25000}](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%20%5Cfrac%7B%20%2825000%20%2A%200.8%29%20%2B%20%28%2040000%2A%201.7%20%29%20%7D%7B40000%20%2B%2025000%7D)
![\alpha = 1.354](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%20%201.354)
